MISSOULA - Persistent fog created by the current weather conditions has prompted the Missoula City-County Health Department to issue a Stage 1 Air Pollution Alert.
Authorities issued the warning as of 8 a.m. Thursday.
The Stage 1 Alert means the air is "unhealthy" for sensitive groups in Missoula and Frenchtown with prolonged exposure outside. That means people with heart or lung disease, smokers, children and the elderly should limit their time outdoors.
The alert means no "visible emissions" from any wood stoves, or other solid fuel burning devices are allowed without a valid Stage 1 Air Alert Permit.
Authorities say there isn't much improvement expected over the next few days, with the forecast for strong inversions and little wind through the weekend and possibly into next week.
The only relief may come with heavy frost in the morning that could help clean the air at times.
